I have a new iPhone SE with SIM-only on iD Mobile.
Roaming in Spain (Movistar), 3G data works ok but no 4G. Roaming and 4G voice/data enabled on phone. Another iPhone (non-iD Mobile) sat next to me also connected to Movistar gets good 4G coverage.
Any ideas? Pretty sure 4G was working at home in the U.K. before this trip.

Thanks for the response.
I did try manual network connection to Orange and Vodafone but got No Service.
I am back in the UK now; 4G working on iD again, no changes to phone setup.
